Abstract RU 2382123 C2

FIELD: process engineering.

SUBSTANCE: film canvas is extruded from polymer melt, cooled and cut into multiple film belts. Prior to drawing, multiple film bands are separated into several groups, each group being separately subjected to drawing. For this drawing mechanism is used incorporating several drawing gadgets that allow separating film bands after dividing multiple film bands into groups.

EFFECT: higher production rate and efficiency.
